Open Access’ NetSpire™ Integrated Communications System is a modular TCP⁄IP (VoIP) based platform providing solutions over wide area fixed and wireless networks. A feature of the NetSpireTM solution is the synchronised time across all control components.

In addition, as their authorised reseller Open Access proudly introduces Spectracom Corporation time products to the Australian market.

Since it was established in the US in 1972, Spectracom has become recognized as a leading designer and manufacturer of GPS (Global Positioning System) synchronised network time servers and precise transmitter frequency control devices.

Spectracom designs, develops, and manufactures Legally Traceable Time® and frequency products that are used by over 15,000 businesses and organisations in a wide variety of telecommunication and IP networks in the public safety, enterprise, telecom, and government markets.

Spectracom’s time synchronisation products are used to improve operating efficiencies, synchronise computer networks, synchronise security systems and to accurately and consistently document events where “Legally Traceable Time"® is needed. Spectracom’s line of wireless clocks and wired clocks, both in digital and analog clock formats, enable users to display synchronised time wherever necessary.

Precise frequency control products provide customers with a GPS frequency reference in such applications as calibration, test and measurement, digital TV, land mobile simulcast and telecommunication network synchronisation.

GPS NTP Time Servers receive time updates from up to 12 GPS satellites and also keep accurate time via internal oscillators. System devices use the GPS NTP Time Server as a time reference to maintain accurate time via NTP across the network. Wireless Clock System Transmitters also receive time updates in this manner and pass them onto any wireless clock devices within range across multiple frequencies (ISM band hopping). Clocks act as wireless network repeaters – receiving time and rebroadcasting – resulting in a wireless mesh network for synchronising time.
